Today is accuracy day for the Diana model 72 target rifle. We had one extra report in this series, and that was on adjusting the trigger. I want to tell you some more of what I have learned about this trigger.

More on the trigger
During the accuracy test, the trigger failed to work two times. The first time I made a small adjustment and got it running again in a matter of a minute. The second time, however, I worked on it for 15 minutes without success. I finally read Part 3 of this report, to see where the two adjustment screws had been positioned when the trigger was working. The camera angle of that photo isn’t the best, so there was still some guesswork involved; but even then I couldn’t get the rifle to fire.

Today, we’re going to look at how to adjust the Diana model 72 trigger. I know this report is needed; because when I searched for information on the Diana model 72 target rifle, this blog was at the top of the list! I wish I had an owner’s manual for this little rifle, as I’m sure clear trigger adjustment instructions are in there. Lacking that, let’s first look at the trigger.

Some topics resonate with more readers than others, and this is one of them. I heard from many Diana model 70 and 72 owners when Part 1 was published, and I hope to hear from more with this installment. New blog reader Harryholic from the UK had just received a new-old-stock model 72 when Part 1 was published. Searching for information on his new rifle, he stumbled across our blog.

Today, we’ll begin looking at an air rifle that I’ve been waiting 3 years to share with you. In 2011 my friend Mac and I were looking at his vintage air rifles to see which ones would be of interest. We actually did a report on his Diana 60 target rifle that was labeled a Hy Score model 810. The rifle needed to be rebuilt, so the velocity was low, but the accuracy was right on. The report was so successful that he decided to test his Diana model 72 youth target rifle next.

Before we begin I have a word about my health. Next Tuesday I’m going to have my pancreas repaired. This is hopefully the final operation I will have to undergo. It will be a major operation where they open me up rather than going in laprascopically, so I’ll be in the hospital for a week or possibly longer to recover. I have written blogs to cover the time I’ll be away, plus I’ll probably have my laptop at the hospital, but I may not be as easy to reach next week. If everything goes according to plan, I should get the drain out of my side and the stent out of my pancreas by the end of this year. And, while I’m away, I’d like to ask the veteran readers to help out the new guys, as you always do.

I’ll be having another outpatient procedure today and will be gone most of the afternoon. I’d like to ask the regular blog readers if they’d help out answering questions from the new people. Edith will be with me in the hospital and will have her computer and also help out with answers if needed.

Photos and testing by Earl “Mac” McDonald.

Readers who have been with us for several months know that my friend Earl “Mac” McDonald has been helping me test airguns while I recover from my hospitalization. Well, Mac is an airgunner, too, and he has a nice collection of fine vintage guns that he would like to share with all of us. So, while we were on the way to the Roanoke airgun show, we discussed the possibility of his testing some of his guns that may not be well-known among airgunners today.
